I'm guessing it's a typo, as I checked the page and the photo is of a 741. You can see it clearly if you select the 2nd picture and zoom in.
Also they haven't even released the specs through official channels from Canaan, which they had talked about having out sometime around now.
Also it looks like the power consumption is still at 1150 W, Not sure because my Russian is non existent, lol
Yeah that clearly is a picture of the 741, very clearly says 7.3TH/s
for whatever it's worth you can translate the page fairly easily.
This is what I got: (sorry not posting pics at the moment)
